(FoxNews.com) - The man accused of killing 2-year-old Bella Bond -- known as “Baby Doe” after her decomposing body was found wrapped in a blanket near Boston Harbor in June -- was obsessed with demons and exorcism and dismissed his brutal handiwork by saying "it was her time to die," prosecutors said during an emotional arraignment Monday.

The chilling details related to the girl’s murder were revealed during the arraignments of Rachelle Bond, Bella’s mother, and Michael McCarthy, Bond’s live-in boyfriend. McCarthy, who has been ordered held without bail, is charged with murder.

“She was a demon anyway and it was her time to die,” McCarthy allegedly told Bond, after the mother found him standing over her while she lay dead in her bed.

McCarthy, 35, was mostly emotionless as he looked straight ahead in court. Bond, 40, held on $1 million bail and charged as an accessory after the fact, wore a hooded sweatshirt and cried several times during the proceedings.
